Types

type ConfigInfo

type ConfigInfo struct {
	Routes []Route
}

ConfigInfo represents service configurator

type Option

type Option func(c *ServiceInfo)

Option overrides a Container's default configuration.

func WithAddress

func WithName

func WithName(name string) Option

WithName 定义服务名称

func WithScheme

func WithScheme(scheme string) Option

WithScheme 设置协议

type OrderServer

type OrderServer interface {
	standard.Component
	// Prepare 用于一些准备数据
	// 因为在OrderServer中，也会有invoker操作，需要放这个里面执行，需要区分他和真正server的init操作
	// server的init操作有一些listen，必须先执行，否则有些通信，会有问题
	Prepare() error
	GracefulStop(ctx context.Context) error
	Info() *ServiceInfo
	Health() bool
	Invoker(fns ...func() error) // 用户初始化函数，放在order server里执行
}

OrderServer ... Experimental

type Route

type Route struct {
	// 权重组，按照
	WeightGroups []WeightGroup
	// 方法名
	Method string
}
